Question

Find the complete range of values of "p” for which $(p^2-7p+13{)}^p<1?$

• A. (-∞, +∞)
• B. (0, ∞)
• C. (-∞,4)
• D. (-∞,0) U (3,4)

Answer 1

The correct option is D

(-∞,0) U (3,4)

Use substitution method,

Put p= 5. Then LHS$>$RHS. Thus, the inequality is not satisfied for this value.

Answer can never be option (a) or (b)

Put p=2. Then LHS>RHS. Thus, the inequality is not satisfied for this value as well. Answer is option (d).
